rocketmq服务的docker启动和配置
rocketmq的默认启动参数占用的内存实在是太大了，小于8G的电脑无法启动，docker中的开发环境又不可能用这么大，通用的该法是改sh文件
修改文件如下
runbroker.sh 默认8G
JAVA_OPT="${JAVA_OPT} -server -Xms${Xms} -Xmx${Xmx} -Xmn${Xmn}"改为
JAVA_OPT="${JAVA_OPT} -server -Xms256m -Xmx1g -Xmn125m"runserver.sh 默认4G
JAVA_OPT="${JAVA_OPT} -server -Xms${Xms} -Xmx${Xmx} -Xmn${Xmn}"改为
JAVA_OPT="${JAVA_OPT} -server -Xms256m -Xmx1g -Xmn125m"rocketmq docker compose启动配置
